ABSTRACT:
A drum capable of being molded in 55 gallon size from high density, cross-linked polyethylene. The drum body or shell has substantially cylindrical walls closed at both ends, respectively, by top and bottom end pieces or heads integral with the sidewalls. The drum includes an integrally molded hollow arcuate chime located at the intersection of the top end piece or head and the cylindrical sidewall and extending circumferentially around the drum. A plurality of rolling hoops located between the top and bottom end pieces extend circumferentially around the drum and protrude sufficiently outward from the drum walls to permit sufficient engagement by the forks of a forklift to support a fully loaded drum thereon. The drum may be reinforced by a plurality of inwardly protruding vertical ribs which run continuously substantially from the top to the bottom of the drum. The top end piece or head includes at least one bunghole integrally formed therewith. The bunghole is threaded to receive a bung and, preferably, is elevated from the plane of the top end piece.
